High Temperature, Time Domain Sensor Interface based on Phase Shifter

Abstract : This paper presents resistive sensor interface circuit for high temperature applications. The presented circuit has a time-domain differential architecture. It is based on the use of voltage-controlled phase shifters to perform the signal conditioning in time domain which makes it more robust the environment's parameters, in particular the temperature. The output of the presented senor interface depends only on relative parameters of the circuit, therefore; a low sensitivity to temperature variations is achieved. The low variation of the circuit output versus temperature has been demonstrated by simulations and measurements of the fabricated prototype.
